I have a Windows 7 Pro computer on a domain suddenly giving this error when trying to login as admin or any user on the system:
"You cannot log on because the logon method you are using is not allowed on this computer"
Since I can't logon locally I edited the domain group policy to allow anyone to logon to all machines. That made the error go away, but now the machine either logs back off immediately or goes to a black screen and sits there where I can’t do anything including bring up the task manager. Safe mode does the same thing.
This computer is less than a month old and I we had no signs of malware (other than this perhaps)
Any ideas of what can be happening?
